The AWS Managed Services Maintenance Window (or Maintenance Window) performs maintenance activities for AWS Managed Services (AMS) and recurs the second Thursday of every month from 3 PM to 4 PM Pacific Time. AMS may change the maintenance window with 48 hours notice. This is for AWS Managed Services (AMS); to perform maintenance activities for managed infrastructures, such as deploying new AMS AMIs.
Your maintenance window is when AMS will apply patching and you determine your maintenance window at onboarding. You can also agree to the proposed patching window provided in your patching service notification, or suggest a different window.
For guidance on creating a maintenance window, see Maintenance Window.
